Hydraulic & Floating Systems
Hydraulic lifts replace cables with cylinders; floating lifts replace pilings with buoyancy. Both solve real problems (fewer wear parts above the waterline, or water levels that swing too far for a fixed lift) and both bring their own maintenance. These guides cover the physics, the trade-offs against cable and piling lifts, and the upkeep that keeps them reliable.
